Open Source has won! Today, most open source developers work for commercial entities and the majority of software and hardware vendors use open source software as key components in their commercial offerings. In this talk we will look at some of the basic dynamics playing out in open source and introduce some mental models explaining them. We will look at the Open Source Flywheel and the Open Source Community Funnel to explain them. We will make a very short excursion into common business models that companies playing in open source use and cover some of the risks that can occur when companies use open source components without fully understanding the potential impact.

4. Developing Open Source Virtualization Technologies since 2003
> 10M Users
Several sub-projects
Xen Hypervisor, XAPI management tools, Mirage OS
Coming: Windows Drivers and Embedded/Automotive
Linux Foundation Collaborative Project
Financially sponsored by Amazon Web Services, AMD, ARM, Bromium, CA
Technologies, Cavium, Cisco, Citrix, Google, Intel, NetApp, Oracle, Rackspace,
Samsung and Verizon

5. Proven Within Largest Hyperscale Operations
The Xen Project Hypervisor is the No. 1 choice for the largest hyperscale clouds in the industry
Examples: AWS, CenturyLink, GoGrid, RackSpace, SoftLayer, Verizon, VirtuStream
Designed for Security
Xen Project software offers a multi-layered approach to security with the ability to wall off intruders
through Driver Domains, Stub Domains, Xen Security Modules
Driving Innovation
GPU Virtualization (e.g. XenGT), Cloud Operating Systems (e.g. ClickOS, ErlangOnXen, Elixir, HalVM,
our own MirageOS and OSv) and ARM Support (new, lean and simple)
Extreme Versatility: Going Beyond Cloud Computing
Our technology is used in a wide range of products and services ranging from server virtualization, cloud
and security. New applications ranging from networking (NFV), automotive to mobile are in the works.

Free software is a
fundamentally superior model
for developing software

19. Daniel Frye
VP, Open Systems Development, IBM
LinuxCon NA 2011
It’s all about collaboration, and working together with other
open source participants. Sometimes this means
collaborating with direct competitors, but IBM gets that this
collaboration on open source creates new resources for
everyone, and they’re not in a cut throat competition for a
finite number of customer dollars.

@Bruce_Schneier
Catastrophic is the right word
[for Heartbleed]. On the scale
of 1 to 10, this is an 11.

25. Growing Codebase
Static and small contributor base
1 person maintaining 100 KLoC =
Underinvestment
Extremely large user base
Critical infrastructure component
Thus impact of Heartbleed is huge

35. An increasing number of companies use Open Source
Clear commercial advantages in doing so
The Open Source Development Model
Has shown to scale and evolve
It creates value and resources for all participants
Not all Open Source projects are the same
Before you use or contribute to a project perform due diligence
Using Open Source is not free
Exchanging cost against risk : failure of project, lack of control, …
Contributing (not just in terms of code) reduces risk
Everyone can help with Marketing and PR
